Kime, Detroit, Mich.,. assignor to American Metal Products Company, Detroit, Mich., acorporation of Michigan Application October V12, 1955, Serial No. 539,982 9 Claims. (Cl. 155-179)- This invention relates to mounting elements'for the ends of wire strips, and particularly to a mounting means which is applicable to'the cylindrical portion of a seat frame.

In the copending application of H. CQFIint, Serial No.

539,981, filed October 12,1955, and assigned to the as-- signee of the present invention, resilient blocks are illustrated for supporting the ends of a wire spring strip on stamped frame members.

The present invention pertains to resilient blocks which are secura'ble to the cylindrical elements of a'supporting frame. The blocks are -so mounted on the cylindrical frame elements as to permit the upperend-thereof to defleet toward the load when the spring strips forming the assembly of a cushion are loaded.

Accordinglyflhe main objects of :the invention are: to provide a resilient element for supporting the .end of a wire spring strip having'securing meansby whichitis attached to a cylindrical frame member in a manner to permit the unattached portion to deflect toward the load; to provide a clip for securing a resilient spring supporting element to a cylindrical frame member which permits the free end which supports the spring end to deflect toward the main body of the spring; to provide an attaching strip to a tubular frame member which secures a resilient member thereon and supports an end of a spring strip in a manner to permit the end to deflect inwardly and downwardly when the spring strip is loaded, and, in general, to provide a resilient support for securing a spring strip to a tubular frame member which is simple in construction and economical of manufacture.

Other objects and features of novelty of the invention will be specifically pointed out or will become apparent when referring, for a better understanding of the invention, to the following description taken in conjunction with the accompanying drawing, wherein:

Figure 1 is a view, partly in section and partly in elevation, of a resilient supporting block for an end of a spring strip secured to a cylindrical frame in a manner embodying features of the present invention;

Fig. 2 is a view in side elevation of the structure illus trated in Fig. l, as viewed from point 2 thereof;

Fig. 3 is a plan view of the structure illustrated in Fig. 1, as viewed from point 3 thereof;

Fig. 4 is a view of structure, similar to that illustrated in Fig. 1, showing another form thereof;

Fig. 5 is a view in side elevation of the structure illustrated in Fig. 4, as viewed from point 5 thereof;

Fig. 6 is a view of structure, similar to that illustrated in Fig. 1, showing a further form of the invention, and

Fig. 7 is a plan view of the structure illustrated in Fig. 6, as viewed from point 7 thereof.

Referring to Figs. 1, 2 and 3, a resilient supporting element 1%) is illustrated having a forwardly projecting upper 1' portion 11 containing an aperture 12 in which the end 13 1 of a wire spring strip 14 is secured. The main body 15 of the re ilient element It) is secured to a tubular frame element 16 by a clip 17. The clip is of U shape having arcuate surface of the tubular frame member 16. In'such relationship, the resilient element 10is securely anchored to the tubular frame element 16 in a manner to permit the upper portion 11 thereof to deflect to the left, as illustrated in Figs. 1 and 3, when a load is'applied to the spring strip 14. This provides a soft edge construction to the rear of the strip and eliminates the pressure at the rear portion of the supporting strip 14 when loaded.

In Figs. 4 and 5 a further form of the invention is illustrated,that wherein the frame member 16 has a sinuous strip 24 welded or otherwise secured thereto. The strip has spaced loops 25 disposed to receive a notch 26' on the lower portion 27 of a resilient supporting member 28 which has an aperture 12 'on its upperend for receiving the end 13 of a spring strip 14. The rear of the lower portion 27 has an arcuate face 22 which mates with the arcuate surface of the tubular frame member 16. The lower body portion 27 of the resilient element 28 is forced into position with the arcuate surface 22 in engagement with the surface of the tubular element 16. The member 28 is securely anchored to the tubular frame member by the engagement of the notch 26 in the U-shaped loop 25 of thesinuous element 24. Withthis arrangement, the upper end of the resilient member 28 is free to deflect inwardl'y'toward the main body of the spring element 14 When the spring elements are loaded.

A similar construction is illustrated in Figs. 6 and 7, wherein a resilient element 31 has a rear arcuate face 22 which mates with the face of the tubular frame member 16 and which is secured thereto by a securing element 32 of conventional form which extends through a slot 33 in the lower body portion of the element 31. The clip 32 has spring fingers 34 which extend outwardly of an aperture 35 in the tubular member 16 so as to engage the wall on the opposite side thereof and securely retain the element 31 on the tubular frame member 16. The upper portion of the element 31 has an aperture 12 for securing the end 13 of the spring strip 14 in a manner to permit the upper end to deflect inwardly toward the main portion of the spring when loaded. The slot 33 in the body of the element permits the deflection of the portion above the slot while returning the portion to its upper position when the spring strip is unloaded.

In any of the arrangements herein illustrated and described, the lower portion of the resilient element 10, 28 or 31 is securely anchored to the tubular frame member 16, with the upper portion free to deflect inwardly when the spring strip supported thereby is loaded. It is to be understood that the sinuous elements may be split on the dot and dash line of Fig. 1, as described and claimed in the above mentioned copending application. This permits a sinuous spring strip having an arcuate end portion to be secured thereby. The portions on both sides of the split are secured together when anchored by the various elements herein illustrated and described to the cylindrical frame member.

What is claimed is:

l. A resilient element for supporting the wire end of a spring having in the lower end a concave face which mates with an arcuate face of a member and an aperture in the upper end which receives the wire end of the spring, and means for securing the lower end of said element to said member with the faces in mated relation, said upper end of the element deflecting toward said spring in response to a pulling force applied thereto by the spring.
